Storm brewing over SHA-1 as further breaks are found

Three Chinese researchers have further refined an attack on the encryption standard frequently used to digitally sign documents, making the attack 64 times faster and leaving cryptographers to debate whether the standard, known as the Secure Hash Algorithm, should be phased out more quickly than planned.

It's not clear that these findings necessitate a crash fix, at least for many purposes. For example, human-readable messages (e.g., email or documents) have context. It is unlikely that a second intelligible message with the same context and hash of the original could be devised. A human would have no problem identifying the second message as gibberish. Even automated processes could make a similar determination fairly easily.
